I HAVE HYUNDAI CAR 2002 SHOW HTIS CODE P0106 AND P0172. WHAT IS THE DEFFRENCE BETEEW MAP/BARO, VAF/MAF.


MAP = mass air pressure, Baro is atmospheric air pressure ( as in barometer), VAF = volume air flow and MAF = mass air flow . The baro sensor alters the air fuel mixture for varying altitudes that the vehicle can travel through. IE from flat plains at sea level to over the rockis.. The VAF sensor measures the volume of air passing through the air intake . The MAF measures the combination of volume and the density of the air flowing through the air intake to adjust the air fuel mixture as cold air is more dense and requires more fuel to burn completely. The MAP measures the vacuum in the manifold after the throttle control to adjust the air fuel mixture in over run situations so that the car will not backfire. All these sensors continually supply input to the ECM which continually compares them with the O sensors and adjusts the injector pulse to ensure complete burn of the mixture in all situations and engine rpm's.
